Obviously you need more environment to build than to clean.  In particular,
there's no need for $INCLUDE to clean, though CL will look for it as part
of a build.  There may be other implicit dependencies as well.  Actually,
I'll bet there are. ;-)  In any case, if the issue is strictly environmental,
you can certainly check the difference in your environment vs the one that
it had trouble running in.  The result of that would be your candidate
problem set.
